As experience designers, we constantly tout the virtues of paying attention to users and creating thoughtfully designed interfaces. This philosophy not only applies to laymen end-users but for the development world as well. With Google Base, Google establishes RSS as the preferred delivery mechanism to getting your content en masse into Google Base.
Bill Burnham sums it up well:
At its highest level, Google’s adoption of RSS represents a further triumph of REST-based SOA architectures over the traditional RPC architecture being advanced by many software vendors. Once again, short and simple wins over long and complex.
Simplicity – whether applied to the development community or the general user community – is a virtue.
